STU FFING-BOX.

SPECIFICATION forming part of Letters Patent No. 406,882, dated July 1G, 1889.

Application lcd May 16, 1888. Serial No. 274,071, (No model.)

To all whom it may concern:

Be it known that I, LUcIUs D. COPELAND, a citizen of the United States, residing at Cainden, in the county of Camden and State of New Jersey, have invented certain new and useful Improvements in Stuffing-BOX and Piston-Rod Lubricators for Steam-Engines; and I do hereby declare the following to be a full, clear, and exact description of the invention, reference being had to the accompanying drawings, which form part of this specification.

This invention has relation to steam-engin es, and particularly to incased engines of the type wherein the piston-rod is arranged and operates within a metallic shell lformin g a portion of the casing, which includes the gearing and other operative parts.

The object of the present invention is to provide a stuffing-box for the piston-rod with an adjustable gland and means for adjusting the same without removing the shell or any portion thereof.

My invention consists in the combination, with the cylinder, piston-rod, and piston-rod casin g, of an adjustable gland and novel means for adjusting the same.

In the drawings, Figure l is a vertical central sectional view of a steam-cylinder, with piston-rod, casing covering the same, and my improved adjustable gland and lubricating device; and Fig. 2 is a transverse sectional view on line a: of Fig. l.

The adjustable gland and piston-rod lubricator consists of a gland A, threaded on its exterior surface, so as to screw into the interiorly-threaded portion B of the cylinderhead B, and provided with a head or fiange a, having radial holes a? at intervals extending through the flange.

A2 is an L-shaped tube adapted to fit into one of the holes a?, and provided at its upper end with a cup as to contain oil, which is fed therefrom through the tube to the piston-rod. The tube A2 leads out from the flange a through a slot or opening A in the adjacent portion of the engine-casing E, inclosing the piston-rod E', and serves as a lever or handle by which the gland is'turned for the purposes of adjustment, the tube being changed from one hole a2 to another, according as may be required in turning the gland a considerable distance.

Having described my invention, I claim- In a steam-engine, the combination, with the cylinder-head Il, provided with an interiorly-threaded portion B, and the exterior] ythreaded gland A, having Hange a, provided with radial holes a2, of the tube A2, passing through the slot A in the casing E, substantially as described.

In testimony that I claim the foregoing I have hereunto set my hand this 12th day of May, 1888.

LUCIUS D. COPELAND.
